It' the circumstances. require it, another dish orVessei--sneh as the performed dish .li-may be employed, in which cosethe seid dish would 'ind u sont upon the upper edge of the boiler, undbetween said boiier :rnd e; suitable cover. In the use oi' the cookereither one or more of these dishes may he employed, and thedishes beingcach provided with wire eyes e, are readily removed i'roni the interiorof the boiler hy o. suituhlebnil (uol: shown) vwith which the eyes c areengaged.

The cover .Fof the cooker is of peculiar format-ion, und being oi' o.diameter somewhat larger than the diameter o1 the boiierbis designed nopass over rue upper portion of said boiler, with iis lower edge restingupon she enei reihig-hongo b, therein formed. ln the upper portion ofthe cover is n diaphragm or plete, (i, from which extends upwardly o.tube, H, through which iuhestcnmpusscs as it; lenves the nluic G- undthe iop of the cover, iinds un oublet through un annular series ofperforations,

y, formed near the outer circumference of the diaphragm G, ns shown inFiga 2.

It will be observed the diaphragm is depressed nenr the annuler seriesof peri'orations, thereby forming a seni; for the upper edge oi' thehoilc.i,nnd permitting the steam, :is it escapes through theperforations, to be discharged in the splice between the outside of bheboiler and the inside of the oever.

From the foregoing description il; is munifcsithat water being pouredinto the trough A oi' the boiler passes through the holes p in thclpluto l und enters the interior of said.` boiler. The slieeni es it isgenerated passes upward through the upper open cud of tho conicalplnte,nnd thence uroundthe dishes into the cover F.' The ascendingstormy, as iii passes through the inbe H, impinges upon the undersurface of the top of the cover and heats suidsurface. The steam, nicerentering the chamber or stennrsp '.rcobetlween tl i o diaphragm G undtop of cover, is deiieeted downward and passes through the annuler:series ofperi'ora.- tions g, und thence into the space between theboiler und cover, where, in its further descent, ib moois currents ol'cold nir entering u series whenee it passes through orher openings, m,Yin the boiler sind is returned to the inside oi the some. By thisarrangement. n eont-innons circulation of steam is maintained during theentire period the cooker is in use, and by di rooting the body oi steam.against the ninler side oi" he top of the cover it. is nienii'est, if :Lcoffee-pot or other vessel he placed upon the Cover, the steam will keepthe contents ol' soin vessel ai; n boiling-heno The boiler A is providedvwith n ihneet., L, by'meons of whieh hoi; water non he drawn fromtheinterior of the boiler forsneh lomos tie purposes moy be desired.
